Right Center Vent Motor (V111)

Right Center Vent Motor (V111)

• The Right Center Vent Motor is installed only on vehicles equipped with the "Comfort" A/C system.

• Currently in this vehicle, all motors are identical in construction. During the basic setting, the control motors are assigned and adapted corresponding to the switching sequence of the wiring. If this sequence does not conform the specification, the control motors will adapt incorrectly and the door control will be wrong. Refer to => [ A/C Control Motor Block Diagram ] A/C Control Motor Block Diagram.

Removing

- Move the passenger seats as far back as possible.

- Turn off the ignition.

- Remove the glove compartment.

- Remove bolts - A -.






- Remove the air guide channel - B - leading to the right instrument panel vent (passenger side).

- Remove the air intake housing. Refer to => [ A/C Unit Air Intake Housing ] A/C Unit Air Intake Housing.

- Mark the connector - A - if necessary (to rule out an interchange in the event several connectors are disconnected at the same time).






- Disconnect connector - A -.

- Remove bolts - B -.

- Remove the shaft - D - of the control motor - C - from the cam plate - E -.

Installing

Installation is carried out in the reverse order while observing the following.

- Insert the shaft - D - of the control motor - C - into the cam plate - E -.

• The control motor does not have a stop; therefore the control motor shaft can be inserted into the cam plate - E - at any position.

- Install the bolts - B -.

- Connect connector - A -.

- Install the wiring harness so that it cannot come in contact with any moving parts (such as the actuating arm).

- Install the removed parts in the opposite order.

- Switch on the ignition.

- Perform a basic setting and the output Diagnostic Test Mode (DTM) on the A/C system using the Vehicle diagnostic tester in "Guided Fault Finding".

• On this vehicle, the control motors are equipped with electronics. During the first basic setting, a new control motor learns its position on the air conditioner and can then be controlled by the Climatronic Control Module (J255) (currently all control motors are identical.) Refer to the Vehicle diagnostic tester in "Guided Fault Finding".

• During the basic setting, the control motors are assigned and adapted corresponding to the switching sequence of the wiring. If this sequence does not conform the specification, the control motors will adapt incorrectly and the door control will be wrong. Refer to => [ A/C Control Motor Block Diagram ] A/C Control Motor Block Diagram.

- Check the Climatronic Control Module DTC memory and erase any displayed malfunction if necessary using the Vehicle diagnostic tester in "Guided Fault Finding".
